Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540200, here are decompositions:
- 11 + 31540189 = 31540200
- 19 + 31540181 = 31540200
- 37 + 31540163 = 31540200
- 53 + 31540147 = 31540200
- 101 + 31540099 = 31540200
- 137 + 31540063 = 31540200
- 191 + 31540009 = 31540200
- 193 + 31540007 = 31540200
Showing the first eight; more decompositions exist.
